Wrong module_load_include path slows down whole site

Problem/Motivation

The recent changes in Drupal 7.33 make every page catastrophically slow (10-20 seconds load time) by exposing an error in version 1.4 of imagecache_canvasactions module. Although the error has been fixed in 1.x-dev since January 2014, there is as yet no release which includes the fix, and therefore any site using the recommended version of this module must almost certainly be unacceptably slow.

The commit in 7.33 that exposes the error: http://cgit.drupalcode.org/drupal/commit/?h=7.x&id=c95d72521d31ff2ae4f84...

The error in 1.4 of imagecache_actions module: #2166715: Typo causes extra query every page load

Proposed resolution

Create a release that includes the fix for this issue.

Original report by Alan Delval

Months ago I did not noticed that my site was slow (from 150-220ms page generation to 900-1100ms on all pages including admin pages), days ago found it and I was using Xhprof and found at least 7000 calls to is_dir, it means that something is wrong with modules, No one module was bad uninstalled, so a module was the problem, I modified boostrap.inc with dpm and found "imagcache_actions" while it must be "imagecache_actions".

I don't know if is done on dev version, but would be good if this not happend because is a stable version.
